Application ined June 2o, i922. semi iro. teased T all whom #may concern; i

Beit known that I, MORGAN D. Kns'r, a citizen of the United States, and a resident of Pendleton, inthe county of Umatilla and State of Oregomhave invented a new and Improved Harvester-Frame Construction, of which the following is a fulhclear, and exact description, y

This invention relates to improvements in harvester frame constructions, an object of the invention being to provide a frame construction which' permits a proper leveling oftheframe regardless of the angle or side hill inclination, and which niain'tainsthe wheels in a vertical position, and the frame relatively low to the ground and at the same distance from the ground at all leveling p0- sitions. I

A further object is to provide a frame of the .character stated, in which the weight of the separator is supported directly-on the main frame and notion the leveling elements.

c A furtherobject is to provide a frame of the character stated, which' permits of proper leveling either on flat ground, or .on side hills, or inclined surfaces, either w1th the header :trame above or below the Ymain frame. .i

AV further ,object is to provide a harvester frame construction which embodies no vel elements .of construction, and novel leveling mechanism which insures a proper leveling of the frame under all conditions,

Y With these and .-other objects in View, the invention consistsvrfin certain novelV features of construction Vand combinations, and arrangement of parts, as will bemore fully hereinafter described and pointed out in the caims. VV 1 In the accompanying drawings Figure 1 is a view in rear elevation illus-A trating my improved frame with the wheels on level ground, the sickle -and reel omitted from Ythe illustration.v n

Figure 2 is a 'vi-ewrsimilar to Figure l but showing the frame whenthe wheels are runningv on a side hill or inclined surface. Figure Sis a view in sidelelevation., Figure 4; is a sectional plan view. Figure 5 is an enlargeddetail View illusbeing tratiiig the leveling shaft and its adjacentA co-operating parts`` 1V represents Ythe main frame and 2 the header `:frame of my improved construction.v

These frames,.1` and 2, are rigidly :secured together .and may be forme-d iin Yvarious ways, but are preferably composed of cross bars asi'ndicated.

T he main frame 1 is made with transverse girders 3 having blocks 4 thereon, on which the separatorV 5 is pivotallyvk supported by means of a shaftf, said shaft being'L projected through cross bars 8 at the bottom of the separator 5.

9 and 10 represent the main wheels `of main frame 1. These wheels 9and 10 are mounted on axles l1 which latter are sup-v ported in( suitable bearings 12, inl wheel frames 13. Thewheel frames 13 are of gen-` eral oblong shape,'are positioned longitudinally of the main frame 1 at opposite sides thereof, and are provided at'their front and rear ends with trunnions 14, which are mounted in bearings 15 in cross girders 3 so that the wheel frames Y13 have a pivotal mounting relative to the main frame; a

The headerV frame 2 adj acentits outer end, is supported by wheel 16. This wheel 16 is mounted to turn on van axle 17,r the latter sup-portedin suitable bearings 18 in a wheel frame 19. i The Wheel frame 19 is provided at its forward and rear ends with trunnions 20 mounted in suitable bearings "21 inthe f header frame 2, so that said frame 19 has a pivotal mounting relative to ther. header frame 2. 'i

Each of the main Wheel frames 13 is provided with I a pair of gearl segments r22, which are secured at their lower ends to the frames 13 and at their upper ends are conso j `These pinions 27 are secured to shafts 28 having suitable mounting in thebars 24 and connected at their forward ,ends by beveled f' gears 29 vwith a transveisefshaft 3 0. This shaft 30 has a worm wheel 3-1secured there-h on, which isili mesh with `the worin32 ona drive shaft 33, the latter being supportedk in.

' siiitablebrackets 34 on the separator 5 and having an ,operating device at its 'freeend On the Wheel frame 19 a post 36 is mounted A and secured in upright position by diagonal braces 37. The upper end ofthis post 36 is connected by a link 38 With an upright j 39, the latter being pivotally connected at its loWer end to the header frame 2 as shoWn frames pivotallyl connected to the main v frame and'to the header frame, Wheels supat 40. The upright 39 is connected by a link 41 With the separator 5, so that the separator and post 36 are compelled to move, and are maintained, in parallelism.

In Lother Words, the angular disposition of all the Wheel frames is maintained in all positions by reason of the arrangement of parts above described, and such angular disposition of the Wheel frames, and necessarily the Wheels carried thereby, is effected through the medium of the drive shaft 33 and co-operating parts. v

It Will-be noted by comparison of figures 1 and 2 that in either a horizontal position or in an inclined position, the Wheels are vall maintained in a vertical position and the frames are at the same distance from the ground, and I Would` have it understood that While I have illustrated the Aheader frame as in the highest position in Figure 2, the mechanism Will function the same and With equal efliciency if the header frame is loWerinost.

Various slight changes might be made in the general form and arrangement of parts describedA Without departing 'from iny invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

I claim: f
